Bayernwerk wants to increasingly integrate battery storage into the electricity grid. The company has now announced locations for new projects.
Grid-serving energy storage systems are to be installed at the Roßbach (Rottal-Inn district) and Bogen (Straubing-Bogen district) substations in Lower Bavaria. On this occasion, Robert Pflügl, Managing Director of Bayernwerk Netz GmbH, commented on the German government's goal of a climate-neutral energy supply by 2045: "For the supply area of Bayernwerk Netz GmbH, this means a multiplication of the generation plants and consumers currently connected to our electricity grid."
With a view to the fluctuating feed-in of renewable energy sources over the course of the day, Pflügl explained that the temporal and local synchronization of generation and consumption and the associated storage of energy are the "key to a successful energy transition". Energy storage systems could shift the timing of energy transport in the event of a bottleneck by operating in a grid-friendly manner, thereby reducing the transmission requirements in the grid and improving the overall grid quality for consumers.
In addition, storage systems could prevent the curtailment of small systems as part of redispatch measures - especially thousands of private rooftop PV systems in Bavaria. The storage systems are to be built at substations where the grid is already heavily utilized today.
The substation in Roßbach (assumed active power 30 to 40 MW) and the substation in Bogen (assumed active power 10 to 15 MW) have been selected as the first locations.
Interested parties who want to operate a storage system there can contact Bayernwerk via the control processes for grid connection. The supplier will then contact them regarding the operation of the storage facility and the grid connection contract. According to Bayernwerk, this process is being tested for the first time at these locations. Following a successful test phase, further suitable locations will be published in the near future.
